ruby - How do I create a prepared insert statement in Sequel?

Question

I am attempting to create a prepared insert statement in Sequel and I am as far as

db[:registration].prepare(:insert)
=> <Sequel::Mysql2::Dataset/PreparedStatement "INSERT INTO `registration` () VALUES ()">

How do I create a statement that is something like the following:

INSERT INTO `registration` (`name`, `email`) VALUES (?, ?)

The documentation is a little bit obtuse and I can't find any examples online.

Answer 1

通过查看他们的 rspecs 想出这一点：

statement = db[:registration].prepare(:insert, :prepared_statement_name, :email => :$email, :name => :$name)
statement.call(:name => "foo", :email => "foo@bar.com")

笔记

传递的键.call对应于在散列中传递的值prepare。所以这也可以：

statement = db[:registration].prepare(:insert, :prepared_statement_name, :email => :$e, :name => :$n)
statement.call(:n => "foo", :e => "foo@bar.com")

Answer 2

ds = db[
         "INSERT INTO `registration` (`name`, `email`) VALUES (?, ?)", 
         name, email
     ]
ds.call(:insert)
